GeForce GTX 1660 Ti vs Radeon RX 480

Intro

Compare those specs to the Radeon RX 480, which comes with core speeds of 1120 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

Radeon RX 480		262144 MB/sec
	Difference: 32768 (13%)

Texel Rate

The Radeon RX 480 is a small bit (approximately 12%) better at AF than the GeForce GTX 1660 Ti. (explain)

Radeon RX 480		161280 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 17280 (12%)

Pixel Rate

The GeForce GTX 1660 Ti should be much (more or less 101%) more effective at anti-aliasing than the Radeon RX 480, and also should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 36160 (101%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
